The recent updates and new features launched by Amazfit and Fitbit in 2025 encompass a variety of improvements in hardware, software, and user experience across their smartwatch and wearable product lines.
Amazfit Updates and New Features in 2025
Amazfit has had an active year with multiple new products and software updates. Notably, in 2025, Amazfit introduced several new models including the Active 2 (Round and Square variants), the Balance 2, Bip 6, and a new Helio Strap wearable. The company also hinted at upcoming releases such as the Balance 2 XT and Balance 2 Runner smartwatches, and possibly another T-Rex series model.
A major highlight is the Amazfit Balance 2 smartwatch, which received a significant firmware update (version 3.22.0.4). This update introduces the BioCharge app, replacing the previous Readiness app, to provide users with real-time insights into their energy reserves. The BioCharge score continuously analyzes energy levels based on sleep, physical exertion, and stress, helping users optimize training and avoid overload. Heart rate changes can now be monitored in real time, and there are improvements in heart rate monitoring accuracy during swimming. The update also adds segmented display support and waypoint reminders, with the golf mode now globally available.
In terms of hardware innovation, Amazfit launched the Helio Strap, a screen-free wearable designed to complement the Balance 2 smartwatch. This strap can be worn on the arm and provides enhanced accuracy for heart rate monitoring, fatigue assessment, and recovery analysis, especially when paired with the Balance 2. It offers up to 10 days of battery life, continuous heart rate monitoring, and supports 27 sports modes without requiring subscriptions.
The company is also preparing to release the Amazfit T-Rex 3 Pro smartwatch, which brings new features like a flashlight, Bluetooth calling, route planning, and integration of the Wild.AI mini app designed for female performance optimization based on menstrual cycles. The T-Rex 3 Pro is expected to retail around £399.90 in the UK market.
Other additions include the launch of the Amazfit Active 2, positioned as an elegant and functional wearable with over 160 workout modes, HYROX race mode, and personalized AI-generated training plans via the Zepp Coach. The Active 2 incorporates features like RestoreIQ for health monitoring, message replies, voice control, and cycle tracking with the Wild.AI app for women. Amazfit has updated its Zepp app to enhance data sharing functions, including a new nap-related tool in version 9.10.x for iOS users.
Amazfit watches continue to focus on ruggedness and outdoor activities, with features like scratch-resistant sapphire glass, AMOLED displays for clear visibility, and 100-meter water resistance supporting freediving and scuba diving. Battery life is advertised up to 21 days for the Balance 2, though intensive GPS use will reduce it.
Fitbit Updates and New Features in 2025
Fitbit has released several incremental firmware updates in early 2025 for models like the Charge 6 and Ace 3, enhancing usability, security, and workout recognition.
The Charge 6 received a firmware update (version 214.24) introducing status indicators and enhanced Bluetooth security, requiring users to reconnect their device during setup to enable these features. Improved exercise auto-recognition now supports six workout types: running, walking, biking, elliptical, rowing, and spinning. The update also improves GPS accuracy by better switching between onboard and connected GPS during workouts.
The Ace 3's firmware updated to version 1.134.84 includes similar improvements, such as easier time checking during exercise mode, access to all exercise modes in the Exercise app, and renaming of heart rate zones for better clarity. The update leverages advanced Google machine learning to improve heart rate tracking accuracy during workouts, offering more precise metrics like calories burned and Active Zone Minutes.
Another notable firmware release for Fitbit devices includes enhanced support for global characters and right-to-left text, expanding notification readability to more languages including Hindi, Arabic, and Vietnamese. The Fitbit Daily Readiness Score is now accessible directly on the device (with Fitbit Premium subscription), giving users ongoing insights into their recovery and readiness status.
The Fitbit ecosystem continues to enhance its user experience with new clock faces available in the Fitbit Gallery app and expanded language support for notifications, calendar events, calls, and texts. These software improvements aim to provide a more personalized and inclusive experience across Fitbit's smartwatch lineup.
